I have a unix class in school and we need to log into the server which is an address like:
something.something.ac.il
in this connection the other students had to download putty , and they use telnet too...
From what I know I can use mac terminal to connect to the school server with ssh, i'v seen some posts say to do something like: ssh username#something.something.ac.il but this docent work for me...I get an error:
ssh: connect to host something.something.ac.il port 22: Operation timed out
I know my port is 23, and we use telnet..
Please help me to log in through terminal...tnx!
I use an app called DOC that works fine that its configurations looks like this:
but i want to use terminal
According to your figure - you are connecting to a telnet server as tripleee suggested. From your mac terminal you should be able to connect using:
telnet something.something.ac.il 23
and you should get prompted for a username and password. Or you could do:
telnet -l username something.something.ac.il 23
In the odd chance that your university is using ssh from a different port (it's not that uncommon, but it would be uncommon to use a port designated to another service). You can specify the port number with ssh on the command-line:
ssh user#something.something.ac.il -p 23

I'm having a hard time viewing Wildfly welcome page on port 8080 + tried apache on port 80 too, and they timeout. I can ssh to the server and using (curl localhost:8080) and (curl localhost:80) show Wildfly and apache welcome pages respectively. I have checked the Security List and Security groups and even opened ALL traffic just to see if they are causing this problem, but unfortunately the problem still there.
I'm using ubuntu 20.04 image and the UFW (firewall) is inactive so the problem isn't from there.
By default every oracle instances come with 2 firewall.
Hardware Firewall (Known as VCN)
Software Firewall (They use a very hard iptables rules and regular ufw doesn't work with that.)
The 2nd option is very annoying and also took me about 3 days to solve my problem. You can follow my following instructions and hopefully it will also fix your problem.
1st you have to open the port on the Hardware Firewall (VCN) and when you believe you have opened the port then by login to the server using ssh use this command to clear the default oracle iptables rule.
sudo iptables -F
But remember whenever you will reboot the server you will need to again run the flash command. So if you don't want to run this command every time after server reboot. Then after running the flash command run this command to save your flashed iptables rules.
sudo netfilter-persistent save
So, you will not need to run the iptables falsh command every time on the startup of the server.

I cant access a server Windows 2008 via RDP. I had to login to the VCenter where the server is located in order to have access. I verified that the Remote Host service is enabled and that the default port for RDP is 3389, the firewall is disabled(it cannot be blocking the connection), the FIPS cryptography is also disabled. So far the only thing that I have found is that when I telnet this way:
telnet [host_name] 3389 the connection is established.
When I telnet [ip_adress] 3389 the connection is also established, but when I telnet with just the host it doesn't allow me to connect:
telnet [host/ip_adress]
What could be the issue here??
Your last telnet is trying to connect to port 25 which is obviously not your target.
I think you should change the remote setting of your windows server 2008 from properties of PC and remote connection tab. There is 2 different security options for remote desktop which determines possibility of user's connections.

I am running Ubuntu 14.04LTS and have FileZilla 3.7.3 installed, I also have a VM running WIN7 with WinSCP 5.5.1.
Under WIN7 when using WinSCP, in the editing dialog under the advanced tab there is a category “Connection” with two options, Proxy and Tunnel . The server I need to FTP or SFTP requires a tunnel, so my setting are Connection through ssh tunnel checked off as yes. The host name Tunnel.rr.net on port 22 and I have to enter in my user name and password, file protcall is set to SFTP, local tunnel port is set to Autoselect and no private key is needed. I know these setting are correct because it works just fine for me I my WIN7 VM, I select the server I need, I see it connect to the tunnel and than my server.
I am new to FileZillaile and the setting options seem to be a bit more extensive, the closest thing I see equivalent is under settings in Generic Proxy. So I set my tunnel host, user name and password which I know are correct because I have no issue with WinSCP.
When I set the Generic proxy to HTTP/1.1 using CONNECT method I get error, Error: Proxy error: HTTP response was absent
& Error: Could not connect to server, when I set it to SOCK 5 I get an error Error: Proxy error: SOCKS proxy returned unexpected version
& Error: Could not connect to server.
Again, I am new to FileZilla so it must be a setting that missing glaring because it is too simple under WinSCP.
So what would the equivalent of “tunnel” be on with WinSCP , in FileZilla?
FileZilla does not support anything equivalent to WinSCP SSH tunneling feature.
You can of course tunnel it through an external SSH tunnel. E.g. via PuTTY or OpenSSH ssh.
See my guide Setting up tunnel using PuTTY for SFTP/SCP session.
(The guide is for WinSCP, but works for any SFTP/SCP client.)

Please forgive the embarrassingly dumb newb question.
Here's the scenario:
As part of a task I have to SSH into a server and create some files. I was given the servers name (some.server.com) and an SSH key (id_rsa.username) to use. I am told to use the username and the provided key to login. Since I am relatively new to the workings of SSH this is what I have done:
I have downloaded id_rsa.username to my Downloads directory.
I have tried loggin in with
ssh -i downloads/id_rsa.username username#some.server.com
But I get ssh: connect to host some.server.com port 22: Operation timed out
I have tried using port 2222 and also 11234 ( I used that port once on a different server).
Is there anything I am doing wrong on my end? I don't have access the server admin to ask any questions so I have to try to figure this out myself.
in my case, I change the rule of ufw, and that rule ban the ssh connect
so run sudo ufw allow sshsolve the problem
"Operation timed out" means that you're not making a TCP connection to the remote server. The remote computer may be down, or there may be a firewall blocking access to the the remote server, or your local computer may not have suitable network access. It's not really possible to say what the exact problem is, based on the information here.
If you're in a corporate network, you should contact your local computer support staff for assistance. It's not unheard of for companies to block outgoing SSH from their corporate network.
Otherwise, if you need help troubleshooting network connectivity, you'd probably get better results on Superuser.

I'm a newbie in working with remote servers and in working with FreeBSD. I want to connect to the FreeBSD running on a virtual machine on my Windows 7 in order to be able to see the files with an explorer interface and be able to copy/paste files to and from it.
I have done this before a while ago using WinSCP but that time it took me 3 days to figure out the configurations I need to make the connection and unfortunately I can't remember them now and do not have another 3 days to waste!!
In my active networks I see to VMware Network adaptors (VMware is the virtual machine I am using) which have the IPv4s: 192.168.134.1 and 192.168.80.1 and when I run "ifconfig" on my virtual FreeBSD there is no IP address (except inet 127.0.0.1). The hostname of FreeBSD is "FreeBSD1" .
WinSCP requires me to fill in a file protocol which I think should be FTP **(correct me if I'm wrong; the other options are SFTP and SCP), a port number (which it sets to 21 by default for FTP) a hostname which I have tried "FreeBSD1", "192.168.134.1" and "192.168.80.1" with my username(root) and password.
When I use the hostname "FreeBSD1" I get the error:
"The requested name is valid, but no data of the requested type was found.
Connection failed."
and for the other two I get:
"No connection could be made because the target machine actively refused it.
Connection failed."
The only thing is, as far as I remember, last time I tried (and succeeded after 3 days) "ifconfig" would show an IP which I think I used as hostname.
** For FTP it also requires an encryption which I set to no encryption. The other options are "SSL/TLS Implicit", "SSL Explicit" and "TLS Explicit".
Any help would be appreciated!
Your Windows machine does not recognize the FreeBSD1 hostname ("The requested name is valid, but no data of the requested type was found" error). So there's no point trying that further.
But it seems that the IPs work, just the FTP port 21 is not open ("No connection could be made because the target machine actively refused it" error).
I would actually not expect that FreeBSD has unencrypted FTP port opened by default. I guess you will have more luck with SFTP (SSH).
